/*
* Test: y2ktmo
*
* Description:
* This test tests the interval time facilities in NSPR for Y2K
* compliance. All the functions that take a timeout argument
* are tested: PR_Sleep, socket I/O (PR_Accept is taken as a
* representative), PR_Poll, PR_WaitCondVar, PR_Wait, and
* PR_CWait. A thread of each thread scope (local, global, and
* global bound) is created to call each of these functions.
* The test should be started at the specified number of seconds
* (called the lead time) before a Y2K rollover test date. The
* timeout values for these threads will span over the rollover
* date by at least the specified number of seconds. For
* example, if the lead time is 5 seconds, the test should
* be started at time (D - 5), where D is a rollover date, and
* the threads will time out at or after time (D + 5). The
* timeout values for the threads are spaced one second apart.
*
* When a thread times out, it calls PR_IntervalNow() to verify
* that it did wait for the specified time. In addition, it
* calls a platform-native function to verify the actual elapsed
* time again, to rule out the possibility that PR_IntervalNow()
* is broken. We allow the actual elapsed time to deviate from
* the specified timeout by a certain tolerance (in milliseconds).
